**Adrian Nickel Alloys**, located in Pulau Ujong, Singapore, is a reliable supplier of **AWS Class ERNiCu-7 MIG and TIG filler welding wire and rod**. This product is crafted for exceptional weld quality in nickel-copper alloy applications. It’s perfect for industries like marine, chemical, and power generation, and is particularly renowned for its outstanding corrosion resistance, especially in challenging environments like seawater, brine, and non-oxidizing acids.
**AWS ERNiCu-7** is a **nickel-copper alloy filler metal** that’s mainly used for **GTAW (TIG)** and **GMAW (MIG)** welding. It features a blend of **nickel, copper, and a touch of titanium** to minimize porosity and ensure a solid weld. This filler metal is ideal for welding **Monel® 400**, **R-405**, and **K-500**, and it works well for joining these alloys to each other or to carbon steels. It offers **excellent corrosion resistance**, **good strength**, and **ductility**, particularly in marine and chemical settings.
